The current price on amazon.com is for the one produced in Canada, that's why it's marked as "imported", if you can wait 2 weeks, USA version will be out, these two are exactly same, but you can get it with a very low price, I think it should be around 20USD, if you can't wait that long, you can try www.futureshop.ca or www.hmv.com, it's only 20cdn there.
